1. IS series single-stage end-suction centrifugal pump is designed ac cording to the capability and size stipul ated i n the internati onal Standard ISO2858, it is composed of pump body,pump cover, impeller, shaft, ring seal, sleeve and suspended bearing units.

2. The pump body and pump cover in IS series are separated from the back of impeller, that is to say in general, back open structure, whose advantages: convenient overhau l,when checking and repairing, the pump body intake pimp,discharge pipe and motor need not to move, just disassemly the middle connector of extended coupling to quit therotor units for overhaul.

3. The pump shell (that is pump body and pump cover)forms the workroom of pump. Impeller, shaft and rolling bearing are the rotors for the pump. Suspended bearing units support the rotors in the pump. The rolling bearing stands the radial load and axial force.

4. In order to balance the axial force of the pump, most of the pumps are designed with sealing rings at the front and back of impellers and a balance hole on the rear impeller cap plate. The reverse of impeller is not designed with sealing rings or balance holes if pump axial force is not powerful.

Q:Can a water pump go out after hitting a deer?
water pumps sometimes just go. just like most other auto parts the water pump will give little or no notice. get it to a garage quick!!! call around in your local area for the best estimate and go with them. replacement can be somewhat costly depending on your car. don't forget to replace the timing chain at the same time. if your car is close to the 80,000 mile mark the timing chain could go soon. to get to the water pump you remove most of the parts in the front end so you might as well replace the timing chain while you already payed to go that far. timing chains go for around$60-$80. i replaced my own in a truck a few years ago ,so take my advice and do both if you plan on keeping your car. i'm from n.h., we have alot of deer related accidents. i hope he was tasty!!!
Q:Determine the isentropic efficency of a water pump?
Well!!!!!!!! Isentroipc Efficiency of a pump = Isentropic Work / Actual Work At state 1, Enthalpy of Saturated Liquid h1 = 413.357 kJ/kg Entopy s1 = 1.29154 kJ/kg-K At state 2, Enthalpy of Liquid at state 2 = 448.042 kJ/kg Now, to find the ideal Enthaply , Enthalpy at 5 M Pa at entropy of 1.29154 kJ/kg-K h2s = 418.462 kJ/kg Thus, Isentropic Work Done I = h2s - h1 = 418.462 - 413.357 = 5.105 kJ/kg Actual Work Done A = h2- h1 = 448.042 - 413.357 = 34.685 kJ/kg Hence, Isentropic Efficiency = I/A = 5.105/34.685 = 14.72%
Q:engine doesnt pump water?
There are 2 water pumps. One in the stern drive, or mounted on the engine which takes the water your in to cool the engine. The other is a conventional circulating water pump, which is important in fresh water cooled engines . Most often it's the impeller failure.
Q:Where online can we find a small water fountain pump?
fountains are us
Q:Automatic water pump!!?
WHAT does it is disrupt always really MEAN?? OK, that said... pumps such as this work to maintain a pressure with two set points even though the regulator only has one indicated.. The lower set point which as pressure drops, the pump turns on, and the upper set point where when the pressure rises to that point, the pump shuts off. When the pressure drops to the lower set point, it triggers the pump to run. When the pressure rises to the upper set point, the pump turns off. If the set point is 50 pounds, it may turn on at 47 and off at 53, or the window could be smaller and on at 49 and off at 51. The air bladder works as a shock absorber, just as the shocks work in your car to smooth the ride. When the pump turns ON there is a pressure pulse that without the air space, would promptly turn the pump off again. This is called short cycling and will cause your pump to on-off-on-off-on-off rapidly. The solution is to refill the air bladder. People with well pumps instead of city water have this problem frequently as the air bladder loses the bubble and does not work as a spring or shock absorber. I have city water NOW, but I used to use a well (which is still operational if I choose to use it) and I experienced pump short cycling the very first year I bought the house. The thing IS, I was ignorant. I missed the thing about a well and a septic tank that also uses a pump to an above ground drain field. YES. I was STUPID because I had NOT paid attention. NOW, years later, I have learned, the HARD way mind you, how these sanitary systems WORK in real life in RURAL America....
Q:can someone eplain to me how the water pump works on an outboard motor?
The driveshaft is always turning. A pinion gear at the bottom of the driveshaft spins the forward and reverse gears, which are freewheeling (in opposite directions) on the prop shaft. The clutch dog is splined and/or pinned to the propshaft, and moved forward (to mesh with the forward gear) or aft (to mesh with the reverse gear) by the clutch dog cradle, which is moved by the up or down motion of the shift rod. The backside of the forward reverse gears are machined with square corners that mesh with the clutch dog. So, the engine turns the driveshaft, the driveshaft turns the gears, the gears turn the clutchdog, and the dog turns the propshaft. Meanwhile, as mentioned, the drive shaft, which is always spinning, is also the water pump shaft. The water pump has a neoprene impeller in a chromed housing; a very tight fit -- the vanes have to be bent over to fit. The center of the housing is offset from the shaft, so the compartments where water is drawn in get smaller as they rotate toward the discharge, which provides enough water pressure to force water through the engine even at idle speed. The impeller is fit so tightly into the housing, that it will generate enough heat to melt and break up without a source of water -- it only takes about 30 seconds of dry running to seriously damage the impeller. to fix the gears, you have to use a gear puller to pull the propshaft bearing carrier. The reverse gear will fall out. Reach in with a long box-end wrench to remove the pinion gear from the driveshaft, and pull the driveshaft bearing housing out with the driveshaft. When you remove the shift rod, the prop shaft, forward gear, clutch dog etc should be accessible. There's a lot of complicated steps to accomplish each of the above, and some critical measurements with near-zero tolerance. Don't do it without a factory service manual in hand.
Q:Possible House Water Pump Problem?
I would still be leaning towards alignment issues are at play here. What I would recommend is putting it on a dyno, not to check the power but so you can see what is happening while the engine is under a power load. I did build an engine once that could not keep belts on, they spun off. I have seen some truly strange things happen. Perhaps the strangest was a thrust bearing allowed to much crank shaft end play and as a result the starter was binding on the flywheel. Yet another was a cam shaft retainer not installed properly allowed the timing chain to snap. Another possibility is the crank damper pulley and not being seated properly.
Q:About drive-belt, timing belt, and water pump of a Tpyota Sienna?
This Site Might Help You. RE: About drive-belt, timing belt, and water pump of a Tpyota Sienna? I have a 2004 Toyota Sienna and it has 80k+ miles on it. I guess it is the drive belt that is making the noise and I decide to have it changed. I can have the timing belt changed too because it is due at 90k miles. The dealer guy told me that I should also have the water pump changed too...
Q:Water is pumped through a pipe of diameter 13.0 cm from the Colorado River up to Grand Canyon Village,?
a) Pressure is the weight of a 1 meter square column of water. The height of the pipe is 2311-564 = 1747 m volume is 1747 m³ density of water is density of water at 20C = 0.998 g/cm³ = 998 kg/m³ mass of water is 1747 m³ x 998 kg/m³ = 1744000 kg weight of water is 1744000 x 9.8 = 17090000 N Pressure is 17090000 N/m² or 17.09 MP b) Cross sectional are of pipe is A = πr² A = π(.065)² = 0.0133 m² one meter of pipe has a volume of .0133 m³ 4300 m³ are pumped per day The water in that one meter of pipe has to be changed 4300 / 0133 = 324000 times per day to handle the flow That is 324000 / (24*3600) times per second or 3.75 times per second. Since the section of pipe is is 1 meter, that is 3.75 meters per second.
Q:How to rebiuld a water pump?
Dont waste your time rebuilding it, just buy one from napa or some auto parts place with a life time warrenty, on something like that your time is worth more then the water pump, and since the pump is having to deal with hot water and corrosion it's possible it might go out again soon or never but with the warrenty it wont hurt so bad.
